17. Acid and Base Equilibrium

pH and pOH

pH and pOH: Crash Course Chemistry #30

If the pH is less than 7 then the solution is acidic, if the pH is equal to 7 then the solution is neutral and if the pH is greater than 7 then the solution is basic.&#160;

If we know the pH or pOH concentration then we can determine the concentration of hydronium ions or hydroxide ions.&#160;

Acids and Bases - Basic Introduction - Chemistry

Calculate the pH of 50.00 mL of 4.3 x 10-7&nbsp;M H2SO4.

16.4 pH Calculations for Strong Acids and Bases | General Chemistry

0.100 moles C6H5NH2

0.100 moles (CH3)2NH

Which of the following solutions will have the lowest concentration of hydronium ions?

The ionization product of Kw is used in this self-ionization equation and ignoring solids and liquids gives the&#160; equilibrium equation as:&#160;

pH stands for the negative logarithmic function of your hydronium concentration, whereas pOH stands for the negative logarithmic function of hydroxide concentration.&#160;

If we have a <a href="https://www.clutchprep.com/chemistry/strong-acids-and-strong-bases">STRONG ACID&nbsp;or STRONG BASE</a> then we DO NOT use an ICE chart to find the pH of solution because the yield of H+ and OH – &nbsp;ions are known.&nbsp;

Determine the pH of a solution made by dissolving 6.1 g of sodium cyanide, NaCN, in enough water to make a 500.0 mL of solution. (MW of NaCN = 49.01 g/mol). The Ka value of HCN is 4.9 x 10-10.

For an basic solution the concentration of H3O+ is greater than the concentration of OH-.

The pH of a neutral aqueous solution is 7.00 at all temperatures.

An acidic solution under normal conditions has a pH value less than 7.00.

If the concentration of H3O+ decreases then the concentration of OH- will also decrease.

The pH of aqueous solutions is less than 7.

Which of the following statements about aqueous solutions is/are true?

Under normal conditions when the concentration is less than 1.0 M the pH scale is between 0 to 14. pH and pOH are connected by the following equation:&#160;

Calculating the pH of a Strong Acid and Strong Base

The pH and pOH of a compound helps to determine its acidity and basicity.&#160;

To determine the pH of a weak acid or weak base we must use an ICE Chart.&#160;

If we have a WEAK ACID or WEAK BASE then we DO use an ICE chart to find the pH of solution because the yield of H+ and OH &#8211; &#160;ions are unknown.&#160;

In a self-ionization reaction two water molecules react with one another, where one acts an acid and the other as a base.&#160;

What is the Kw of pure water at 20.0°C, if the pH is 7.083?
